In this paper, spectral domain method of moment (MoM) is utilized to analyze frequency selective surface (FSS). The RWG basis functions are used to model the FSS geometry. The Fourier transform of the basis function can be expressed in a new analytical form, and the fast convergence characteristic can reduce the computation time of impedance matrix. Numerical results are given to demonstrate the validity and efficiency of the proposed method.
